SPECIFIGATION forniing part of Letters Patent No. 530,979, datedDecember 18, 1894.

' Application filed June 4,1894- Serial No. 513,401. (No model.) i

To all whom it may concern: I

Be it known that I, FREDERICK W. WIL- LIAMS, a citizen of the UnitedStates, residing at Minneapolis, in the county of'Hennepin, State ofMinnesota, have invented certain new and useful Improvements inDrilling- Maohines, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements indrilling machines of tion will hereinafter appear and the novel featuresthereof will be specifically definedv by the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figure 1 is a side elevation of my improveddrilling machine, with portions broken away, and showing it adapted forhorizontal drilling by full lines and for Vertical drilling by dot-.

ted lines. Fig. 2 is a plan of the carriage with the other partsremoved. Fig. 3 .is a detail in side elevation showin g the manner ofbracing the vertical portion against the device to be operated upon.Fig. 4 is an edge view with portions removed. Fig. 5 is a detail partlyin elevation and partly in section.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, Adesignates thetruck or carriage which is designed to support the working parts andhaving wheels A and a pole or tongue A as seen in Figs. 1 and 2, itbeing designed to be moved easily about from place to place as may bedesired. This carriage is provided upon its upper face with thesubstantially centrally-disposed longitudinal slots at extending fromend to end and in which the feet of the upright support are fitted towork,- and with the transverse slots a intersecting withthe longitudinalslots a to permit of the removal of the upright from the carriage whendesired, as will be readily understood from reference to Figs. 1 and 2.This carriage bed is further provided upon its upper face. with theradial grooves or channels a which are undercut or of a substantiallyinverted T- shape asshown in Fig. 1, and with the transverse slots awhich are also undercut and which communicate with the longitudinalslots a as seen in Fig. 2.

B arethe upright parallel bars of the machine. One is provided upon itsouter face with the rack-bar or teethJ). They are socured at their lowerends to across plate B and'suitably braced as by the braces b as shownin Fig. 1, and to the under face of this plate are secured the yokes Bin which are journaled the rollers b which are designed to travel uponthe upper face of the bed, and

these yokes extend below the rollers and are formed into the lateralextensions, flanges or feet 12 as seen best in dotted lines in Fig. 1where the bars are shown in their horizontal position,these feet beingdesigned to travel in the channels or grooves a, and a 'which areundercut to receive them.

The drill-carriage is mounted upon the bars B for adjustment andsuitably mounted in one portion thereof is the shaft 0 provided with ahandle 0 and carrying a pinion D meshing with the rack b as seen best inFi 4and upon this same shaft are the ratchets D as is shown best in saidFig. 4 with which engage the pawls or dogs 61 which are mounted in acasing as shown and provided with the thumb pieces d as seen in Figs. 1and 4. The side pieces of the carriage G embrace the bars 13 and areconnected by the plate a in which the ratchet'dogs are mounted.

E is a plate or bar having at opposite sides the vertical portions ewhich are formed with the curved slots e as seen best in Fig. 3 andthrough which pass the bolts E which secure thesame to the side portionsof the drill-carriage and by which the plate or bar may beadtoo justedto give the desired angle orinclination to the drill. To this plate orbar is secured the plate F having the depending side barsf the lowerends of which are pivotally mounted on pivots f held in the sideportions 0 of the carriage, as seen best in Fig. 1. Supported by thisplate F is the yoke Gin which is mounted the inclined shaft G, whichcarries the bevel pinion G and which shaft is provided with a swivelconnection g with the shaft g from which power is conveyed from anysuitable source, which may be if desired, a motor of any form mountedupon the carriage A. In suitable bearings in this yoke is journaled thehorizontal shaft H which carries a bevel pinion H which meshes with thebevel pinion G as seen best in Fig. 4, and this shaft is extendedthrough between the bars 13, its other end being supported in a bearingh in the plate or arm it supported on the drillcarriage and the end ofthis shaft carries a drill-holder or chuck of any well known form. Thedrill is fed forward by means of the handle H on the end of the shaft H,which is screw threaded as seen at h in Fig. 3, its hearing it beingscrew threaded to receive it.

The machine may be held to its work in any suitable manner. In Fig. 3 Ihave shown the bar B, as provided with a plurality of holes ifor thedetachable engagement of a removable bolt I which secures thereto abrace bar I having an adjustable portion 1" with an opening to receive arod I which is held at its ends in any suitable manner to the boiler Jor other article being operated upon, and the machine may be adjustedalong this rod if desired.

With the parts constructed and arranged substantially as above set forththe operation will be readily understood.

The truck A may be moved to the position desired and then the bars Bwith their accessories adjusted as occasion may require. The drill isadjusted to the desired height and angle and is revolved through themedium of the bevel gears,-the drill being fed forward by the handle andscrew shaft.

When it is desired to use the machine for vertical work, I provide a rodJ 2 which may be held between the bars 13 by a removable bolt J and anupright K which is detachably secured to the bed of the carriage bysuitable means as bolts j j to one side of the longitudinal center ofthe machine as indicated by dotted lines in Fig. 2 and its upper end isprovided with a horizontal portion K which extends over the longitudinalcenter of the machine as shown in Fig. 1 and indicated by dotted linesin Fig. 2, and upon this horizontal portion is mounted to swivel abifurcated support L.

When the bars are to be turned from the vertical into the horizontalposition in which they are shown by dotted lines in Fig. 1 the rod J 2is secured in position by its bolt as shown in Fig. 1 and the upright Ksecured in position with the said rod resting in its bifurcated swivel.The bars and their carried parts are then moved so that their feet willmove out of the lateral channels a and then the bars are swung into thehorizontal position with the rod J and swivel as a fulcrum and afterbeing brought to their horizontal position they are swung round insubstantially a lengthwise position with relation to the truck A and theremovable support M having been placed in position at the rear end ofthe carriage as shown in Fig. 1 and indicated in Fig. 2, a hook clamp N.is engaged with a lug or projection n on the said support M as seen inFig.1 and the nut tightened so as to hold the bars to the support. Thework may be clamped to the bed of the carriage by bolts or other meansengaging in the undercut radial channels provided therein for thatpurpose.

When the machine is again to be used for horizontal or radial drillingthe upright K and rod J are removed, the hook clamp disengaged from thesupport M and the bars 13 placed back in their vertical position.

The support M may be removed or left in its position as may be desired.

Modifications in details of construction may be resorted to withoutdeparting from the spirit of the invention or sacrificing any of itsadvantages.

What is claimed as new is-- 1. A portable drill having itsdrill-carriage mounted for adjustment upon the truck th ereof andcarried by a support mounted for pivotal movement from a vertical to ahorizontal position or vice versa, and a support on the truck for saidcarriage in its adj usted position substantially as specified.
